Serial No. 767,129.

. will prevent longitudinal movement of the rails of railways.

Another object of the invention is to provide means of automaticallytightening the grip of the anchor upon the rail.

To the accomplishment ofthese objects and suchiothers as may hereinafterappear, as will be readily understood by those skilled in the art, theinvention comprises a rail anchor-embodying features of construction thecombination of elements and arrangement of parts having the general modeof operation as herei/hafter described and claimed. i 1

The preferred embodiment of the invention is shown in the accompanyingdrawings, in which I i Figures 1 and 2 are, respectively, asectionalvi-ew anda side elevation of the rail anchor. Fig. 3 is anendview ofthe device,

showing the position of the dog when being forced. into place.

4 is a plan view of the bottom of the clamp.

Similar letters apply to similar parts throughout the several views.

In the embodimentofthe invention illus trated in the drawings A istherail, B

is a clamp constructed. to accurately fit the bottom of the rail andengage withthe flange attheside of the rail. C is a dog; D is a tie orsleeper. The clamp B is constructed witlr'a face E, arranged in anyconvenient position b'elowlthe rail to bear upon the side of the tie D,and a rib or web F, which is notched at G? to receive the dog. Thesurface of this notched portion G of the web F which will engage withthe dog C is preferably cylindrical. The clamp B isalso provided with ajaw H" to engage with the flange of the rail at one side. The dog C isIconstructedwith a hook portion I to engage with the notch G in the webF and the engaging surfaces K.of-the dog C and the clamp B arepreferably cylindrical. An arm L of the dog engages with the uppersurface of the flange of the rail on the side opposite to the clamp jaw.The dog C is provided with a projection M which may conveniently bestruck with a hammer to remove the dog.

The device is placed in position by placing the clamp B with the face Eagainst the tie and the jaw H engaging with the flange of the rail. Alight blow with a hammer will set the clampupon the rail. The dog C isthen placed with the hook portion I engaging the notch G in the web F,and the arm L engaging with the edge of the flange of the rail oppositeto the clamp jaw ll. The dog is then driven into place by blows with ahammer, or in some other suitable manner, and the clamp l3 is in thisway drawn into contact with the under surface of the base of the railand at the same time subjected to a. transverse I C is finally inposition will generally effectually prevent any movement of the rail Aupon the tie D, but should slight movement occur the dog C, whichisrotatably held at its lower end I on the clamp B and has its arm 'Lengaging with the rail flange will move forward with the rail and assumethe position indicated by the dotted lines in Fig. 2. This action willautomatically increase the pressure be tween the clamp and the rail andthe anchor is therefore automatically tightenedand further movementprevented.

Obviously some features of the invention may be used without others andthe invention may .be embodied in "widely varying forms within the scopeof the artisan.
